What is a PROVEN 331 Combo...as fas as H/C goes....? anyone know em'?? Im puttin a stock motor in my car for winter....ditchin the Performers and the E cam.....im thinkin about doin a 331, 10.5:1 on pump 91 octane. it already has: 3.55's/ full exhaust/ ignition/ cooling system/ 190 intank, AFPR, 24lb. i will also be running the prfessional products Typhoon intake with their elbow and 70mm TB...polished of course. It will all be cleaned up and port matched (those intakes are a little shabby, the price isnt though..lol).....and to top it off some polished plain TIGGED sheet metal valve covers....what you guys think?? NOW! bring on the Head and cam combos...... Thanx!! -Scott
sorry cant help u on the H/C but, but can u run 11:1 on 91 octane???u must be running a pretty hot cam to get rid of cylinder pressure.check that out or ull get a lot of pinging???
My bad 10.5:1.....i dont see why not. 90% of the japenese made cars are running around on 11+.....to be specific S2000's are 12:1
Im leaning towards Victor Jr's and the Comp Cam XE274HR. CAM SPECS: IN: EX: DUR: 224* 232* LIFT: .555 .565
